Australia's Cam Bolton has claimed back-to-back silvers while rising star Josie Baff snatched bronze at the Snowboard World Cup in Canada.

Bolton outpaced Czech Radek Houser and Germany's Leon Ulbricht at Mont Saint Anne to claim his third and fourth podium places of the season - and a career-best final ranking of third in the men's competition.

The three-time Olympian from Mornington Peninsula in Victoria was beaten to gold in each of the weekend's races by world No.1 and local favourite Eliot Grondin.

"First time in the top-three (on the overall standings), and these things are pretty hard to win, so very happy to come away with it," Bolton said.

"Always tricky to back up the second race in a double event, but the sun has come out ... I was able to come up and put in a pretty good performance."

Canada's Grondin ended well ahead in the men's standings to finish the season on 952 points, with Olympic champion Alessandro Hammerle second (604) and Bolton third (552).

Australian young gun Baff earned a final ranking of fourth in the women's competition after claiming third on Sunday.

The 21-year-old, from Jindabyne in the NSW Snowy Mountains, finished ahead of world No.1 Chloe Trespeuch.

Britain's Charlotte Bankes claimed gold with Italian Michela Moioli second.

Baff has finished on the World Cup podium nine times in her career - five of them coming this season.

"It was super-fun, I really wanted to do one better after yesterday," said Baff, who finished Friday's racing in fourth.

"I would have loved something more, but I am very satisfied with the third.

"It was super-tight racing with all of the girls. We all showed our best riding and wanted to give it our best for the last two races of the season."

Trespeuch ended the season first on the women's standings on 792 points, followed by Bankes (757), Moioli (704) and Baff (608).

Baff's teammate Belle Brockhoff crossed the semi-final line in third place to seal a spot in Saturday's small final, finishing seventh.

Fellow Australian Mia Clift was named female rookie of the year after a promising first World Cup season.

The 19-year-old from Melbourne took out a personal best finish of eighth on day one at Mont Saint Anne, finishing the season ranked 19th.
